INVALID-BED.

To all whom it may concern:

Be it known, that 1, JOHN M. KELLER, a citizen of the United States of America, and resident of Youngstown, county of Mahoning, and State of Ohio, have invented certain new and useful Improvements in Invalid-Beds, of which the following is a specification.

This invention relates to improvements in adjustable invalid beds, and more particularly to a bed which is especially adapted for use in hospitals.

Theprimary object of the invention to,

provide a bed composed of pivotally-connected sections which may be readily adjusted Without disturbance of or annoyance to a patient resting thereon, and having a removable seat portion, said bed being particularly designed for use in some cases of a pendicitis and septic peritonitis, wherein, a ter the usual surgical operation has been performed, it becomes necessary or desirable that the patient be held in what is known as the Fowler position that is, in a semi-reclining position with the knees elevated-.for facilitating the natural drainage of pus from the peritoneal cavity and also the giving of the continuous saline injections so necessary in such cases for diluting and carrying away the poisonous matter.

A further object of the invention is to provide a bed by means of which the hips and shoulders of the patient are held up Without the aid of straps, and whereby the body of the patient is caused to assume the Fowler position without inconvenience or discomfort.

A still further object is to provide a bed which may be readily adjusted for raising and lowering a patient or invalid 'restlng thereon to any position between a straight reclining posture.

position and an upright sitting And a still further object is to bed or chair which is particularly adapted for use in cases of fractured legs, having a pair of separately-adjustable legsections adapted for use in; independently adjusting the positions of the legs of a patient.

With these and other objects in view, the invention finally consists in the particular construction, arrangement and combination of parts which will hereinafter be fully described, reference being had to the accom- Speeiflcatlon of Letters Patent. Patented Sept, 27, 1910,

Application filed November 11, 1808. Serial No. 462,146.

panying drawings, forming a part of this specification, in which- Figure 1 1s a side elevation of the invention; Fig.2 is a view of the same partly in top plan and partly in broken section; Fig. 3 is a longitudinal section of the same on the line 3-3, Fig. 2; Fig. 4 is a similar section, enlarged, on the line 44, Fig. 2; Fi 5 is a horizontal section of the gearcasing on the line 5-5, Fig. 4, showing the gearing in top plan; and Fig. 6 is a perspective view of a supporting-latch.

Referring to said drawings, in which like reference-numerals designate like parts throughout the several views-1 indicates a rectangular metallic frame, formed preferably of angle-iron, adapted to be mounted upon a bed-frame 2 in any suitable manner. Mounted upon each side of said frame 1 at suitable points is a gear-casing 3, in which casings are journaled the ends of a pair of transverse shafts 4 and 5, the latter having rigidly mounted thereon a pair of arms 6 Which support the rectangular back-section 7 of'a bed-frame which consists of said backsection 7', a rectangular seat-section 8, and a pair of U-shaped leg-sections 9.

-The adjacent ends of the back-section 7 and the seat-section 8 are ivotally connected, extensions 10 carried by the former being mounted upon adjustable pivot-pins '11 projected through longitudinal slots 43 in the sides of said seat-section. The opposite end of said seat-section has extensions 12 and 13 which are pivotally connected to the ends of the U-shaped sections 9. Each of said sections 9 has at its opposite end a supporting-leg 14 having a laterally-directed pin 15 projected through a slot 16 in the frame 1 with an adjusting-nut 17 thereon whereby said leg may be held in any position to which it is adjusted along said slot 16. The supports for the said section 8 consist of a pair of arms 18 mounted upon a transverse shaft 19 which is journaled at its '0 posite ends in gear-casings 20, similar to t e casings 3, mounted upon said frame 1.

mattress spring 22 of a wire-netting type stretched thereover for supporting a mattress s'ection 23, and the sections 8 and 9 have Stretched thcreover a second mattress spring 24, the latter being divided to admit of independent movement of the two legsections 9. A second mattress section 25 is mounted upon said second spring 24, as shown, said mattress being divided in a manner similar to that of the spring 24 for admitting of independent movement of said leg-sections.

lnclosed within each of the gear-casings 3 is a novel form of gearing, which consists of a bevel-gear 26 fixed upon the shaft 4, a spur-gear 27 fixed on the end of the shaft 5, and a shaft 28 having a bevel-gear 29 upon one end thereof in mesh with the bevelgear 26 and a worm 30 about the body of the shaft 28 and in mesh with said s ur-gear 27. The neck portions of said sha t 28 are journaled in bearings formed by transversely: directed webs 3 and 3 respectively carried by the casing sections 3 and 3 The shaft 4 has a stem 31 projected outward from the casing 3 which is adapted for receivin thereon a crank or hand-wheel (not showng whereby said shaft may be rotated.

The gear-casings 20 inclose gearing which is precisely similar to that inclosed by the casings 3. As is obvious, when it is desired to elevate the back-section 7 to any position between a straight reclining position and an upright position, the shaft 4 is rotated forward, and this action, through the gearing, causes the arms 6 carried by the shaft 5 to rise and force said back-section 7 upward and forward, as shown in dotted lines in Fig. 1.

To adjust the seat-section 8 and leg-sections 9 to cause them to assume positions wherein the patient will be held in a partially reclining and partially sitting posture, with the knees elevated, as shown in dotted lines in Fig. 1, for forming a thigh-rest and a leg-rest, the shaft 21, which has a stem 51 similar to the stem 31, is rotated in a rearward direction, and this action, through the gearing inclosed by the casing 20, swings the arms 18 and the seat-section carried thereby upward and rearward. As the seatsection is raised, the leg-sections are inclined upward, the pins 15 carried by the legs 14 sliding rearward in the slots 16.

As is apparent, chance retraction of the }parts is prevented by the use of the gearing erein shown and described. 1

Provided in the seat-section 8 is a small removable rectangular frame 38 which has mounted thereon a plate 39 and which is normally held in place by underlying latches 4O pivotally mounted on the frame 8. Said plate 39 has fixed thereon a lurality of coil mattress-springs 41 on whic is mounted an oval-shaped mattress section 42 which fills up a similarly-shaped opening in the mattress section 25 and in the mattress spring 24. Extensions 49 of the cloth covering of the mattress section 42 are suitably fastened to the frame 38 so that the mattress section 42, springs 41, plate 39 and frame 38 may be together removed from the oval-shaped opening in the seat-section when the latter occupies substantially the position illustrated in dotted lines in Fig. 1, for admitting of the use of a commode or bed-pan placed beneath said section, or for admittmg of the use of a syringe or catheter.

When it is desired to adjust the seat-section to adapt the same for the use of a child or. other patient whose le areltoo short to permit of comfortable sitting with the legs flexed naturally at the knees, the pivot-pins or bolts 11 are moved forward along the slots 43 to shorten the length of the seat,- the rear end of the latter bein thus permitted to project rearward behin the upraised back-section 7. Thumb-nuts44 carried by saidpins or bolts 11 are manipulated for holding the sections in adjusted positions.

Each supporting leg 14 has a longitudinal shank 45 with a longitudinal slot 46 therein, and said shank is adjustably connected to the side of the U-shaped section 9 by means of a bolt or pin 47 projected from the section 9 through said slot 46 and having a thumb-nut 48 thereon. By adjustment of one or both bolts or pins 47 along the slots 46, one or both ofthe leg-"sections of the bed may be elevated to a horizontal position when the seat-section occu ies substantially the position shown in otted lines in Fig. 1, a feature which isparticularly desirable in cases of fractured legs or other leg affections.

Anti friction rollers 50 are provided on the ends of the arms 6, as shown.

From the foregoing it will be seen that I provide an extremely simple and convenient form of invalid or hospital bed which may be manipulated to raise or lower a patient occupying it to any dwired position without subjecting the patient to the disturbance or annoyance ordinarily attending movement from a reclining to a sitting posture, and vice versa.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
